public: FeatherAlphaBlendCommand( RasterImage^ sourceImage, LeadPoint sourcePoint, LeadRect destinationRectangle, RasterImage^ maskImage, LeadPoint maskSourcePoint ) |
Parameters
- sourceImage
- RasterImage object that references the source image.
- sourcePoint
- LeadPoint structure that contains the origin of the source rectangle. The width and height are the same width and height for the destination rectangle.
- destinationRectangle
- LeadRect structure that contains the destination rectangle.
- maskImage
- RasterImage object that references the fade mask. If you want to combine the two images just with opacity set this property to null.
- maskSourcePoint
- LeadPoint structure that contains the origin of the mask rectangle. The width and height for the mask rectangle are the same width and height for the destination rectangle.
Run the Leadtools.ImageProcessing.Effects.FeatherAlphaBlendCommand on an image.
